Title: Toner recovering member exchange period notifying mechanism for image forming device
Inventor: KATO KOJI
IPC: G03G15/08
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To detect the exchange period of a toner recovering member, with high reliability and a simple constitution, in an image forming device provided with plural developing devices by notifying an operator of the exchange period of the toner recovering member, when the sum total of the number of the operation times of toner feeding members reaches a reference number of operation times previously set. SOLUTION: The toner feeding members 13 and 14 are driven according to the output of toner concentration sensors provided in the developing devices 4 and 7, to supply toner in toner tanks 15 and 16 to the developing devices 4 and 7 and further, previously set so as to supply a specific amount of toner. The number of the operation times of the toner feeding members 13 and 14 is counted by counters 17 and 18, to recognize the degree of the consumption of the toner in the toner tanks 15 and 16. When the sum total of the counters 17 and 18 reaches a fixed number, an exchange signal for a toner bag 12 is outputted. Therefore, even if the developing device is exchanged in the process, the quantity of the toner in the toner bag 12 can be accurately recognized.

Abstract: PURPOSE:To prevent damage of an internal combustion engine, for instance, due to excessive racing at the time of starting the engine, by setting the engine speed for cutting fuel supply at the time of high-speed operation of the engine proportionally to the temperature of cooling water, and setting the above fuel- cut engine speed at a low value as the engine temperature is low and the viscosity of lubricating oil is high, for instance, at the time of starting the engine. CONSTITUTION:A micro-processor 8 at first calculates the engine speed for cutting fuel supply to an internal combustion engine 1 on the basis of the output of a water-temperature sensor 12 furnished to the micro-processor 8 via an A/D converter 14. Further, the micro-processor 8 detects the actual engine speed speed from the output signal of a crank-angle sensor 17, and at the same time, judges from the output signal of a gear switch 16 whether the gear position is neutral or not. In case that judgement is that the gear position is not neutral, the actual engine speed is compared with the engine speed for cutting fuel supply to the engine at the time of its high-speed operation that is determined to correspond to the temperature of cooling water. Further, in case that the former is judged to be equal to or higher than the latter, fuel supply to the engine 1 is cut by switching the flag to '1'.
